These are the years Washington had its five warmest months of March:
Based on the weather that followed Washington’s five warmest springs, the Gang found only one of them had a warmer-than-normal summer. And it’s not what many would consider warm, landing at 78 degree average temperature.
Looking beyond March, and examining the whole winter from 1981 to 2010, the Gang found the combination of warmer than normal winters and a warmer March was followed by the warmer than normal summer about 64 percent of the time.
With a warmer than usually spring, odds are in favor that Washington’s summer will be warmer too.
For allergy suffering taking note, the tree pollen count on Thursday was the highest in the past 13 years at 2,124.
